Answer:
m<5=115°
Step-by-step explanation:
Hi there!
We're given the measure of <7 as 115° and we need to find the measure of <5
vertical angles theorem is a theorem that states that angles that share opposite angles that share the same vertex (corner point) are congruent. An example of a pair of vertical angles on the given transversal would be <8 and <6
<5 and <7 are also vertical angles
since m<7=115°, by vertical angles theorem, m<5 is also equal to 115°
Hope this helps! :)
